This study aimed to enhance the adhesion effect between the central line of bonding in the production process of cigarette filter rods and the hollow filament segment within,an exploration was undertaken into the impact patterns of specific water-based adhesives on their applicability during the entire course,encompassing performance and application methods.Through rheological investigation,distinct specifications of water-based adhesives were scrutinized for their rheological characteristics,with an analysis of the thermal and mechanical properties of the adhesive films.Further assessment was conducted regarding the drying speed and wetting performance of these water-based adhesives,including tests on their adhesive strength,thereby speculating on the factors influencing the ultimate adhesion strength.The results reveal that under similar solid content conditions,all water-based adhesives manifest commendable shear resistance,with adhesives of higher viscosity exhibiting heightened strength and resilience.Consequently,the adhesive films derived from such adhesives also possess increased strength.However,excessively high viscosity in water-based adhesives can impede their drying speed and dampening capacity on filter rods,thereby affecting their adhesion properties.Hence,water-based adhesives of moderate viscosity demonstrate the most optimal adhesive effects.
